All right my new motor is almost wrapped up and had to pick the injectors and since that is the number one problem with these trucks I decided to go with Don M because I have never heard anything bad about his injectors. But I was wondering with all the cracked injectors and leaky ones has there ever been any problems with the Don M flux 2 100hp injector for the common rail. Also how many people are running them and what should I watch out for. I cannot afford anthor rebuild on this motor as they are not cheap. I went ahead and went with the Don m Flux 2 injectors, pro street puller 66, cam, Don M valve springs, arb head studs, airdog fuel system, with edge juice and maybe the bullydog if I need it to pull, and the haisley dual disc street puller clutch. I think I should have a pretty wicked setup then when I get the money and stage 2 cp3.

 

The Flux 2's I just installed were one of the best single mods to date. They knocked almost .7 off my 1/4 mile time, helped with spool-up, and burn really clean (zero smoke at WOT).

 

That would be because you have TWO turbos. Mine smoke like crazy. Got to get me that 2nd turbo.

 

my flux 3.5 smoke like acoal train if I am too heavy on the throttle but after the silverbullet lights I get a slight gray haze at wot with the pyro at less than 1500

 

Man I wouldn't think 1.8's would smoke especially with the A3k... what's up with that??

I have to ask because I am looking at 1.8's as my next mod... what HP were they? 80?

 

does your pump keep up with these? no cut out or anything?
Im thinking of going bigger if I pull mine out again. they for sure seem to help with a big single charger it helps it light up alot better

 

Don,

Pls see Nathan's e-mail. Time is getting short for me.

Tks,

Pat

 

How do the flux 2's tow? Anyone pull a load with them in?

 

You also have TWO turbos, so you have nothing to worry about. The A3k is not a very big turbo and we're talking around 600hp of fueling. Dyno runs have shown that Don's ratings are on the conservative side. I know a truck with a Smarty that the 1.8 showed 110hp on the dyno. We're expecting 90+ out of them on my truck.

 

I have surging issues with the 1.8s and my A3k. With MPI compounds you won't have to worry about towing with the 2.0s. They should be real nice.

 

I have towed with my 3.5's and 66 charger and it towed fine. It wasn't heavy but still 10K.

 

Sloverado I would love to see what the smoke factor & egts look like with your truck towing 10,000 lbs with 3.5 fluxs and a single 66, 10k seems like a decent load to me how far and how long did you pull ?

 

Does anybody know the ratings on the flux injectors? Ie, what hp to expect out of 2s, 3s, 3.3s, 3.5s, etc?

Sloverado, are you runnin a single pump, or duals?

 

There was min smoke with Smarty on 1 and Flux 3.5's. I run a singe stage 2 Floor It pump but will be going to twin pumps this month. With the ProStreet 66 on a big hill it would hit 1100-1200 but stayed in at around 800 most of the time. That is the heaviest load I have pulled with thes inj. That was 320 mile trip.

 

The Flux 1's are 40hp and the 2's are 100hp. Can't really help you with the rest of them though.
